From a stock view point you are correct, GJ. Dexron has friction modifiers to allow smoother shifting. Type F does not. Naturally, if you put Dexron in a Ford or any other AT calling for Type F you will trash it in short order. If you have a restored ride where you aren't looking for maximum performance then Dexron is fine.
Type F has been run for years and years in Mopar and GM performance builds to enhance shifts, at least in old school transmissions (727, 904, PG, TH350-400, etc.). I honestly have no idea on newer trans models. work
As far as mixing fluids, I should clarify I WOULD put Type F in a GM or Mopar trans if it was all I had on hand but WOULD NOT consider Dexron in a Ford. up
Basically, it's what your looking for in your end result. boogie
